the whirl D, is provided for insertion in the casing B in a manner to besubsequently set forth. The extreme lower end 26 of the portion ofspindle C is recessed upwardly to provide a bearing point for suspendingthe spindle C and whirl D in the manner to be subsequently set forth.The whirl D may be of the ordinary type, including the belt receivingportion 27, intermediate the lower and upper circumferential flanges 28and 29 respectively. The whirl head 30 is provided, above the flange 29,and having suit-able ribs 31 thereon for engaging the bobbin. Theannular flange or circumferential portion 28 of the whirl D ispreferably provided with a depending bead 32, extending annularly uponthe bottom face thereof, and upon the outer marginal edge. A socketrecess 34 is provided extending axially and upwardly in the Whirl D fromthe bottom flange 28, and for the free reception of a portion of thecasing B therein.

The bolster E is of novel formation, and is provided for insertion intothe casing B from the screw threaded end 19 of said casing B, andadapted for receiving the de pending portion of spindle (J. This bolsterE includes an upper cylindrical portion 36, and a lower cylindricalportion 37, said portion 37 being of greater external diameter than theportion 36 to provide a shoulder 38 at the juncture of said portions 36and 37. A tapering bore or passageway 40 is provided axially through theupper and lower portions 36 and 37 of the bolster E, and in fact adaptedfor reception of the lower portion 25 of the spindle C when the same isassembled therein. A groove 41 extends longitudinally of the lowercylindrical portion 37, and is provided as an oil passagewayintermediate the casing B and outer surface of the bolster E, when saidbolster is assembled in the casing B. Suitable radial apertures or ducts42, are provided, in the groove 41, which extend and communicate intothe passageway 40. Various other radial ducts 43 are provided in theportions 36 and 37 to communicate between the exterior and interior ofthe bolster E. The extreme lower marginal end 44 ot' the enlargedportion 37 of bolster E is provided with adjacent lugs 45, extendingdiametrically opposite on the exterior surface of the portion 37, andadapted for sliding in the slots 20'of the casing B in a manner to besubsequently described. The adjusting means F of the spindle mechanismincludes the member 45, which is in reality a screw threaded plug havingthe screw threaded shank portion 46 thereof for engagement upwardly inthe screw threaded aperture of the casing E, the plug 45 having anexterior knurled head 47 for manual adjustment of the same. The innerand top surface of the shank portion 46 is provided with an arcuateseating depression 48 for receiving a ball bearing element 49. Suitablewasher elements 50 of a predetermined thickness and gauge are providedintermediate the head 47 of the adjustable bearing 45, and the lowermarginal end of the casing B, in order to accurately gauge theadjustment of the plug 45 in the casing B.

In assemblage, the bolster E is properly inserted in the passageway 14of the casing B, the reduced or smaller portion 36 of said bolster Ebeing first inserted through the screw threaded opening 19, andpositioned in such manner that the lugs 45 slide upwardly in the slots30 through the screw threaded portion 19 of casing B. The plug or stepbearing 45 is next adjusted, as above described, in the casing B, andwhereby the bolster E is supported upon the upper face of the shank 46.The bearing member 49 is of course, disposed axially of passageway 40 ofthe bolster E, and extends upwardly in said passageway and free fromcontact of the sides thereof. The spindle C is next assembled to thecasing B as above described, and whereby the lower portion 25 thereof isproperly inserted through the upper opening 13 of casing B and extendsinto the passageway 40 of the bolster E, the lower bearing end 26 ofsaid spindle 0 resting upon the ball bearing 49. The bearing collar 51welded or otherwise rigidly mounted on the spindle C within the whirlsocket 34 also bears in the marginal groove 52" on the upper end ofbolster E. In this position, the whirl D will be suspended over thecasing B, and whereby the upper end 12 of said casing B extends into thedepression or socket of the whirl D. In this position, the annularflange 28 is spaced just above the lubricating reservoir 10 and acts asa cover therefor. The annular bead 32 de pends circun'iferentially aboutthe upper marginal edge of the lubricating reservoir 11, andconsequently prevents dust and the like from entering in said reservoir11. The nut 45 is properly adjusted in the casing B, whereby the entireweight of the spindle E and whirl. D is borne by the anti-friction orball bearing member 49, and the bolster F. The depending portion 25 ofthe spindle (.3, of course, rotates in the bolster E, although there isvery little clearance interu'iediate the elements. Due to the lugs 45",the bolster i) will be prevented from rotating relative to casing B.

hen removing the bobbin from the spin dle C, said spindle G and whirl Dare apt to ride relative in the casing B, due to the speed at which thesame are rotated. To prevent disconnection of the spindle Cand whirl Dfrom the casing B, a pawl or dog element 55 is provided, having an uppertooth 56 adapted for engagin the upper surface of the annular flange 28to limit or lUti define the movement of the spindle G with respect tothe casing B. An outwardly projecting arm 57 is provided whereby thepawl 55 may be rocked upon a pivot- 58, for removing the tooth 56,whereby the entire spindle element C and whirl D may be re moved. Thepivot element 58 which supports the pawl 55, is supported by the radialcars or lugs 60, whereby the pawl 55 is supported intermediate said lugs60 and with just sufficient friction that the pawl 55 may maintain anyposition in which the same is manually placed. Normally, the tooth 56 ofpawl 55 is spaced outwardly from the belt engaging surface 27 of thewhirl D, by the belt (not shown), which engages the portion 27 and willnot come into contact with the pawl 55.

A lifting element 62 is provided pivoted to the pin 58 which supportsthe pawl 55, for lifting the whirl D and the spindle G, whereby thelubricating reservoir 11 may be uncovered for access to the interiorthereof for refilling purposes. The lifting lever (32 preferablyincludes a pair of spaced arms 63 and 64:, provided upon their outerfree ends with heads 65, which engage diametrically opposite sides ofthe head 10 and normally rest just beneath the bead 32 of the coverflange 28 of whirl D. The arms 63 and 64, are in fact pivoted to the pin58 adjacent the outer sides of the lugs 60, said arms 63 and 64: havinga bight portion 67, which in fact is a hand or finger engaging leverextending outwardly and just below the finger engaging portion 57'of'pawl' 55, to facilitate operation of the lifting device 62. 1

, aste or some other absorbent material 69 is placed in the lubricatingreservoir 11, for retaining a suflicient amount of lubricant forlubrication of thespindle mechanism, The lubricant flows into thepassageway let through the duct 22, where the same flows freely aboutthe outer surface of the upper portion 36 of bolster E, since the sameis spaced from the inner sides of the passageway 14:, due to theenlarged cylindrical portion 37 of said bolster E. The lubricant flowsthrough the various ducts 43 and down through the groove 41 through thevarious ducts 42 therein and properly lubricates the point bearing 26 ofspindle G. V

The adjusting mechanism F has been provided to compensate for wear uponpoint 26 of spindle G, and on bearing collar 51 and in marginal groove59;. This wear will, of course, be very minute. To maintain an accurateadjustment, the very thin and ac curately gauged washer elements 50 areprovided, for securing a proper adjustment.

From the foregoing it can be seen that a spinning spindle has beenprovided, in which the parts thereof are of practical con struction, andcan be assembled in accurate the reservoir 1.1 are of novelconstruction,

and provided to simplify operation.
